BACKGROUND OF THE INVENTION
(1) Field of the Invention
[0001] This invention is related to a hand-winder assisting rope clamping structure for
use in cargo transportation operation.
(2) Description of the Prior Art:
[0002] Presently traditional cargo transportation operations in general are mostly made
through the operation of fastening cargo piling on the truck using ropes and tighten
cargo on the hook rods installed on both sides of the frame of the truck. However,
to accomplish the operation of fastening cargo, tremendous labor effort has to be
made to complete the cargo fastening work. Sometimes, under the situation when the
fastening operation is not correct, the cargo might be scattered around and damaged,
resulting indirectly in safety problem of worker's injury at work.
[0003] Therefore, to ensure the tightness of fastened cargo and reduce the problem of work
injury while at the same time provide a strength-saving and practical cargo fastening
tool, the industry has developed a product called hand-winder, as illustrated in Taiwan's
patent No.
325845. The structural design of such product mainly consists of a main body and a pulling
handle pivoted axially to a hub with a pair of ratchets fixed on the hub to carry
together during rotation. A sprawling is used to restrain the ratchet for unidirectional
rotation. A flat belt is further wound on the hub so that the hub undergoes unidirectional
rotation together with the winding of the flat belt through the up and down pulling
control action of the pull handle. The flat belt therefore gradually tightens the
cargo in order to achieve the purpose of fastening cargo, and the implementing operation
is easier and saving effort.
[0004] However, though such hand-winder could improve the labor expense and achieve the
result of saving effort in operation as well as reducing the danger in operational
safety of fastening operation and increase the convenience, there are also other inconvenience
and drawbacks brought with it. The major drawbacks are:
[0005] 1. A flat belt is required to match with a set of hand-winder for the operation.
Therefore, the longer the load on the truck the more hand-winders are needed to prepare.
The cost of installing hand-winder which the transport business requires to purchase
is also relatively increased, which is not really cost effective.
[0006] 2. Each hand-winder after fastening cargo has to be placed on the fastened cargo
and is taken down only after unloading cargo. Therefore, both sides of the truck are
hung with arrays of hand-winders. This does not only increase the weight of the truck
but also might severely affect traffic safety if the hand-winders drop off due to
mechanical failure.
[0007] 3. Each of the arrays of hand-winders must be kept away after unloading cargo. Therefore,
this creates a storage problem if more hand-winders are used, resulting in more trouble
and inconvenience and causing severe wastage in work hour.
[0008] From the analysis described above, we know that the drawback of such hand-winder
is mainly in the hand-winder which cannot be removed freely after completion of fastening
cargo but has to remain on the cargo. Indeed, this has the pressing need for improvement.
SUMMARY OF THE INVENTION
[0009] The main purpose of this invention is to provide a tool for assisting the clamping
of rope during the process of tightening cargo and further to achieve the purpose
of stretching the rope through the operation of hand-winder in order to resolve the
